About Video

This video clip shows two-dimensional transesophageal echocardiography. Aortic dissection. Short-axis view. F shows the dissection flap in the aortic root (AO) in close proximity to the origin of the left main coronary artery (LMCA). Dissection flaps (F, arrowhead) are also noted in the aortic arch (ACH). More intense flow signals are visualized in the perfusing lumen (PL) as compared to the nonperfusing lumen (NPL) and this serves to differentiate them. Arrow points to a communication between the two lumens detected by color Doppler flow examination.
